International Fatigue Database EAF Public Meeting Washington DC, 25 Sept 2018 K. Mottershead1, R. Tregoning2, T. Austin3, and S. Cuvilliez4 1Wood PLC 2U.S. Nuclear Regulatory Commission 3European Commission JRC 4Électricité de France This project has received funding from the Euratom Research & Training programme 2014-2018 under grant agreement N 662320
EAF Public Meeting Washington DC, 25 Sept 2018 NRC has created separate fatigue databases containing laboratory specimen data NRC-JNRA (formerly JNES) created database containing results in air & LWR environments for carbon, stainless, and nickel materials NRC-EdF created database containing results for stainless steel materials in air.
Data sharing was achieved through existing agreements between the NRC and JNRA and NRC and ASN.
Separately, other database efforts have been pursued internationally INCEFA+ project Incorporated some MHI data during initial INCEFA+ phase In 2017, a broader collaboration was proposed to create an international database Initially, develop agreement between NRC, JRC, and INCEFA+ partners Expand participation to other organizations that will abide by the terms and conditions of agreement
Background
2
EAF Public Meeting Washington DC, 25 Sept 2018
- 5-year European project under Horizon 2020
- Project approved in Feb. 2015 and initiated in July 2015
- 16 organizations participate
- Objectives
- Conduct testing on austenitic stainless steels in air and LWR environments to study 3 parameter effects (surface finish, mean strain/stress, hold times) and their interaction (~200 tests)
- Propose new methods to account for these effects INCEFA+ Project 3

EAF Public Meeting Washington DC, 25 Sept 2018 Participants Initial: NRC, JRC, INCEFA+ participants Wood PLC is the coordinating organization for INCEFA+
Future: other interest organizations agreeing to conditions Technical Approach JRC will provide data administration as well as data entry training and support All sides will develop a common data template to govern data submission All sides will upload data to MatDB and provide appropriate access.
Agreement Approach Use existing NRC/Euratom agreement as the umbrella agreement Develop an addendum describing the data sharing terms and conditions Complete technical and legal review by signatories and finalize the addendum Agreement Structure 4
EAF Public Meeting Washington DC, 25 Sept 2018 Online database application designed for storing and exchanging engineering materials data from mechanical testing.
Data model dates to the 1980s and was established in collaboration with national laboratories in the US and Japan A MatDB data set consists of a test result and accompanying metadata.
Modules for data entry, data retrieval, and data citation.
Manual, semi-automated and fully-automated data entry is supported.
Data retrieval module supports open, registered and restricted access MatDB 5
EAF Public Meeting Washington DC, 25 Sept 2018 Technical staff from all sides generally agree on terms and conditions Final review from INCEFA+ participants is nearly complete Wood PLC consolidating proposed changes Final US NRC and JRC review will occur once INCEFA+ proposed changes are added Signing and implementation of the agreement is planned for Fall 2018 Once agreement is initiated, will consider participation by CSNI organizations that have expressed interest (e.g., Korea, Czech Republic) and other interested organizations Current agreement contains provision that allows additional signatories upon unanimous consent of existing signatories Agreement Status and Plans 6
